I was unclear. I have IP configuration data written in
/etc/sysconfig/network-scripts/ifcfg-<ifacename> (RHEL/CentOS/Fedora
location). That's how NetworkManager gets what it needs to run
networking (as long as it's not blocked in the ifcfg-<device> file
specifically.
The new method is to have resolve.conf "built" each time the network is
started up.
I use bind managed through Free-IPA for DNS for my domains.

Every time you stop a school, you will have to build a jail. What you
gain at one end you lose at the other. It's like feeding a dog on his
own tail. It won't fatten the dog.
